Cell printing is a promising technology in tissue engineering, with which the complex threedimensional
tissue constructs can be formed by sequentially printing the cells layer-by-layer. Though some cell
printing experiments with commercial ink-jet printer show the possibility of this idea, there is a long way to
implement cell printing in engineering. To get a better understanding of drop on demand piezoelectric cell
printing, a cell printing experiment system with commercial piezoelectric ink jet printing head and configurable
drive circuit is developed. And a series of cell printing experiment with yeast cell is performed to study the
influence of drive parameters, cell solution density and viscosity of the solution on cell survival rate, droplet
density and orifice status. The experimental results show that the cell solution density and its viscosity are key
issue for cell printing with commercial printing head, and a large drive pulse width is helpful for printing the
cell solution with a high cell density and viscosit.
